Getting “No message available” error with Spring Boot + REST application

Question

I have created demo Spring Boot project and implemented Restful services as shown here

@RestController
public class GreetingsController {
    @RequestMappin         


        

Answer 1

In my case I called the wrong path via ribbon.

@FeignClient(name = "currency-exchange")
@RibbonClient(name = "currency-exchange")
public interface CurrencyExchangeProxy {

    @GetMapping("/exchange/{from}/to/{to}")
    PairRateDto callForExchangeValue(@PathVariable("from") String fromValue, @PathVariable("to") String toValue);

}

Remote currency-exchange service didn't have handlers for /exchange/{from}/to/{to} path.

So for nonexistent URL I've got 404 which is fair with "No message available" which is strange.
